PULLING-OVEB MACHDIE.

Application filed June 26, 1911.

To all whom it may concern:

Be it known that I, Roxann F. McFnnLr, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts have invented certain Improrements in PullingOrer Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures This invention relates to pulling-over machines and is shown for purposes of illustraticn as embodied in a machine similar to that shown and described in prior Letters Patent No. 1 0-29387, granted on my application June 11, 1912.

Prior to this invention power pullingover machines have been so organized that erery shoe is pulled to the same extent, or ith the same force, which is determined by the adjustment of pulling springs, and there is no practical way for the operator of those machines to govern the pull in accordance with the requirements of individual shoes. While each of the three gripper levets of those machines has a handle by which the gripper associated with it can be moved after the machine comes to rest, it is impractical for the operator under working conditions to make use of these handles to the power-driven pulling action of the prior machines- An operator is obliged to employ one hand and sometimes both for presenting the shoe in proper relation to the several grippers and for holding it so that the upper will be securely seized when the machine is started and there is not time or opportunity for the operator to change his pcsition and reach up to the gripper levers between the time when the side grippars which close lasL have seized the upper and taken control of the shoe and the time when the pulling movementis completed.

A feature of this invention consists in means by which the operator can contr l the upper pulling movement which is effected automatically hr the grippers of a poweroperated machine. In the illustrated emhcdiment of this feature of the invention the machine is provided with a no el dampmechanism comprising a single dashpot-connectcd by an equalizer to a plurality of: grippers and operating to retard by equal Specification of Letters Extent.

resistance the automatic updraw movement of the side grippers and render that movement comparatively slow so that it is extended considerablv beyond the short period during which the power is applied to the machine. The illustrated updraw controlline means further comprises a hand lever connected at one end through the equalizer to the side grippers and havin; its handle end located in position for the workman to engage it with one hand during the pulling of the shoe efiected by the power mechanism after he starts the machine with the usual foot treadle. By the use of this feature of the invention the operator is given abundant time to perceive how the shoe is responding to the pull exerted by the grippers and he can manipulate the controlling lever either to increase or to diminish the extent of the pull on the upper or, if he desires, to stretch the upper repeatedly so that each shoe can be treated according to its particular requirements As I am advised it is new by this inyention to provide a power driven pulling-over machine with means controlled by the hand of the operator during the pulling operation to determine the extent of the pulling movement In accordance with a further feature of the invention means is provided which is constructed and arranged for operation duriug a yieldingly eflected upper stretching operation to lock the machine against continued stretching action on the upper. In the illustrated embodiment of this feature of the invention the lockimz means can be made to interrupt the pulling action of the grippers at any point in the gripper move ment; at which the operator decides that the shoe has been pulled enough. The power mechanism completes its normal movement and stores power in the updraw springs after the grippers are stopped- The operator can thereafter release the locking means and allow additional, manually controlled stretching of the upper by the power stored in the springs. The locking means is shown as arranged to be released automatically at the end of the machines cvcle.

In accordance with another feature of this invention the e is also provided no el means fo controlling the extent and rate of the pulling movement of the toe gripper relatively tothe side grippers It is desin able that the toe gripper operate before the side grippers pull because the upper should be drawn forwardly on the last before the action of the side grippers causes it to bind around the last. and because such initial operation of the toe gripper straightens the upper along the sides of the last and posi- LlOIlS it. longitudinally of the shoe for the side grippers to seize it at the proper points. There are however two disadvantages that have been encountered in the past. The first is experienced particularly in making shoes on high toed lasts where the upper bridges from the instep to the top of the toe high above the ball and is very difiicult to draw down to the wood at the ball against the full tension of the toe gripper. The second dificulty is experienced in connection with the use of a foredrawing movement for the side grippers. This movement is intended to ten the vamp forwardly along the sides of the shoe. If the toe gripper oompletes its forward pull and the side grippers thereafter are given their foredrawing movement there is a tendency to twist the upper. The object of this portion of the invention is to meet these conditions while preserving the advantage of pulling by the toe gnpper To this end a feature of the Invention consists in dividing the automatically effected movement of the toe gripper and providing adjustable means to limit that portion of the toe gripper movement which occurs before updnw of the side grippers begins, with or vvlthout provision for causing the latter portlon of the toe gripper movement to be effected in oompanv with a forward move ment of the side grippers It is furthermore a feature of this inventlon to operate the toe and the side grippers together to draw the entire upper forwardly with or without first drawing the upper forwardly by the toe gripper alone.

The movement of the side grippers 1s efiected through a spring and in accordance ith a feature of this invention an adjustable stop is provided to limit the extent of that movement. In the illustrated embodiment of this feature of the invention the machine is equipped with a hand lever by which manual foredrawing can supple meat the automatic foredrawing and the comes to rest with the hand lever against a ap after having effected foredraw during the first part of the side grip per operation- The stop is so arranged that it can be rendered inoperative whereupon the said foredraw spring will eflect a further foredrawing automatically after the updrawing movement has been completed.

These and other features of the invention more important details of con e ssemhi t ee ste r? will be in ure scription, reference being had to the accompanying drawings. and will then he point ed out in the claims.

In the drawings, Figure 1 is a side elevation of a pulling-over machine equipped with this invention: Fig. 2 is a perspective view of the new parts and connected mechanism; Fig. 3 is a vertical sectional detail, and Fig. 4 is a pelspective view from the rear and one side for showing better than appears in Figs. 1 and 2 the new parts which have been applied to the machine for embodying this invention.

The machine comprises a head furnishing bearings for a driving shaft '2 controlled by a clutch and clutch rod 3 and having the operating cams of the machine including cams connected by springs 4 and rods 5 with the rear ends of updraw levers 6 from the front portions of which the grippers are suspended for seizing and pulling the upper at the toe and at the sides of the ball. The clutch causes the machine to come to rest with the upper under tension as in Fig. 2 to permit the upper to be adiusted bv the tip straightening lever 9 or by manipulation of the handled front ends of the side gripper levers 6.

In accordance with this invention an up draw control lever 20 is pivoted on the fulcrum rod 22 and has fast on it a pinion or toothed @gment meshing with a toothed arm 2-1 of a rock-shaft This rockshaft has an arm '26 extending over the updraw levers and having a broadened head engaging the upper sides of the levers. This arm is free to turn about its longitudinal axis so that its head can adapt itself to different relative positions of the levers 6 caused bv the upper pulling up more on one side of the shoe than on the other as sometimes happens- A bridle 2S embraces the head of arm 26 and also the levers 6. so that the updraw levers can be lifted as well as held down by the hand controlled lever 20. This construction and mounting gives to the headed arm 26 and the bridle '28 the function of an equalizer in the connections between the side gripper levers and the lever 20 and bet een the said levers and the dash-pot 40. The machine frame has a se ment ratchet 30 adapted to be engazed bv a pawl rod 32 which slides in the lever '20 and normallv stands by gravity out of engagement with the ratchet but can be raised to stop the pulling movement by finger manipulation of its lateral extension 33. Bv e gaging the pawl rod 3'2 with the ratchet 30 the action of the updraw springs 4. tending further to stretch the stock or to take up stock as the elasticity of the upper responds to the pull of the grippers, is arrested.

A cvlinder 40 is pivotally supported at 42 upon the frame back of the npdraw control leveritl ands piston-head 43 therein is ooniting the pawl -force to the control lever 20 to retard it to a nected bv plunger 44 with the lever '20 to be moved thereb By means of this laslipot the updraw of the grippers is retarded and consequcntlv will continue. unless stopped by the pawl rod 32, after the power mechanism has come to rest. At its rear end the cylinder has a puppet valve l adjustably held up hr a screw 46.

In the use of the machine the shoe is presented as usual to the toe and side grippers with the sole against the sole rest 16 and the toe against the toe gripper and held by the right hand while with one foot the oporator depresses the starting treadle and, either before or after stretching the ma chine. he may seize the updmw control lever and through that lever amume manual coutrol of the updm power driven movement of the erippus The rise of the grippers is retarded bv the resistance of the air in the cylinder 40 while the power from the driving. and cams is stored in the springs 4. Llfhe operator watches the efiect of the pulling movement upon the upper of the shoe and as soon as the particular upper be- 5 2 Stretched has been properly pulled to its last he arrests the pulling movement by set- If in doubt he applies greater extent than the air resistance does and allows the upper to stretch as slowly as the best results for that particular shoe may require If desired, he (an! interrupt the stretching at anv point and perform any in operation that may be needed as, forexample adjustment of the partially tensicned upper by the tip straightening lever 9 or otherwise When the lever 20 is then released the upper will be again pulled by the force stored in the springs 4, which can be supplemented by manual force applied to the lever 20' and bridle 28 if desired, in the direction to raise the grippers for repeatedly the upper. This procedure is espe wfnl in tightening the up er about last at the hack of a high too. The equal connection formed bv the swiveled Stem'of am '26 of the rock-shaft permits updraw levers to take relative positions determined by the resistance of the stock on the two sides of the last respectively and furthermore permits the updraw levers to be relatively moved for adjusting the upper transversely about the last while said levers are under control of lever '20 or nder control of the clash-pot 40. .3. 44. This procedure is especially useful in tightening the treatment of the slices heretofore found only in hand \vrrk. as well as allcrding the important advantage over hand work which is obtained by the use of a plurality of grippers pulling the entire slice at one operation. This invention makes the work easier for the operator because it relieves him of much of the need for reaching up to the updraw levers and straining at them to pull the upper more or to relax it to meet the demands of the shoe in hand. Vv'hen, in a later portion of the machine's operation, the updraw cams lower the grippers the control lever 20 is swung forwardly and the pawl 32 is automatically disengaged frcm the ratchet 30. The puppet valve can be adjusted to cause the air pressure to retard the updraw Little or much as may be desired or can be fully opened- The machine is shown as having connections from the side gripper levers only to the dash-pct and the crntrcllever 20.

In addition to the adjusting screw 46 a loose stem 4$ may be employed which can lift the valve and provide for a manual control of the egrem of air from the cylinder without dependence upon adjustment of the puppet valve. As a means for enabling the operator to hasten at times the completion of the pulling movement, as for example when he sees that the condition of the shoe will fully warrant speedier work, I have shown a thumb piece 50 locatcd on the outer side of control lever 20 and having a bell crank 52 at its upper end to which is connected a rod 54 upon the upper face 55 of which, at its rear end. the stem 48 rests The rod has an inclined face 56 that moves over a rest 58, Fig. 2, depending from the cylinder 40 and causing the rod to lift the valve when the thumb piece 50 is pressed upon. If it is desired to out out the resistance offered by the dash-pot to the upper stretching movement the thumb piece will be raised to cause the hell crank 52 to actuate the stem 48 to open the valve 4-5.

The new control for the updraw movement mechanism above described is pref erably employed in combination with a foredrawing mechanism which is similar to that sho n in United States Letters Patent No. 1,145.38L granted July 6, 1915 on my prior application by which the side grippers are caused automaticilly. alternatively bv a hand lever 91, to pull the upper forwardly at the two sides of the last This foredrawing mechanism includes a bar 90 attached at its rear end to an upstanding lug on a longitudinally reciprocating slide 86 which derives its movement from a cam roll 87 standing in a track in a cam block on the main driving shaft. To this bar 90 is connected the lever 91 depending from a rock shaft 93 journaled in the machine head, and on this rock shaft is a toothed segment which communicates motion through an intermediate gear 94 to a rack 95. This rack has on its front end a guide way 96 inclosing a block which is a part of a pivotal coupling between the rack and the adjacent side gripper. It may be explained that the intermediate gear 94 is a part of a rod that extends across the machine and at its other end has similar toothed engagement with another rack like the rack which is similarly connected to the side gripper which is adjacent to it The relation of this foredrawing mechanism to the tip straightening niechanismcontrolled by the lever 9 is fully in said Patent 1,145.38'1 andneed not be described here. By these connections it will be seen that the side grippers are forwardly during each-power operation of the machine. The cam track for the roll 87 is so formed that this actuation takes'place i'minediatelv after the side grippers the upper and before the uplifting movement of the side grippers has caused the upper to bind upon or frictionally engage the last toan extent to retard the foredrawing of; the upper obiecti'onably. It will also he noted that while the foredrawing movement is efiected vieldingly, as by a spring 97 in the bar 90, Fig. :2, it is not afiectedby the retarding action of the dash pot 40. The handled and of lever 91 forms means by which a mannal'f oredrawing be efiected. or a reverse movement of the grippers, and morwver in connection with the hand lever 26 said lever 91 afiords provision by which, if the shoe is not satisfactorily pulled. the updrawing tension relaxed and the upper foredrawn as the-appearance of the shoe may show to be necesary to locate the tip seam or to make the upper fit properly on the last.

The machine is provided. see Fig. 1, with an'adinstable stop screw 109 that is located in the'path of the lever 91' to limit the foredmwing movement in accordance with requirements of the class of shoes being pulled over, the execs movement from the driving cam being up by the spring 97. This stop 100 is by a rotatable block having a spring detent 102 which allows the stop to be turned out of the wav of lever 91 'when further foredrawing mo esment'is desired on a particular shoe.

The toe gripper le er 5 is extended rearwardly at 60 beyond its operating earn slide and has an adjustable screw 61 located over the operating cam slide 62 for the side grippers for engagement the slide 62 whereby aid screw engages the slide and the independent upd'raw of the toe gripper. The extension '60 and screw 61, regulate amount which the toe gripper can pull the upper forwardly before the side jaws seize it. In other words, this feature of the invention provides for adjustably regulating the extent of foredrawing efl'ected by the toe gripper relatively to the side grippers. An advantage of this is the avoidance of bowing or curving forwardlv the middle of the tip seam which has sometimes resulted from excessive pulling by the toe gripper before the side grippers took hold. This result was liable to occur when the uppers were large for the last. The combinations herein employed provide for regulating the foredrawing of the side grippers and also of the toe gripper. It is also to be noted that the latter portion of the foredrawing by the toe gripper is delayed until the side g pp rs are prepared to take part in the foredrawing movement wherebv provision is made for pulling forwardly the sides and middle of the upper together. It is to'be noted that the updrawing movement of the toe gripper is now divided into two steps, the first of which is independent of the side grippers and the second of which is dependent upon movement of the side gripper operating slide 62.
